Tenho um problema, ou algo mal configurado,
Tenho valores em tempo real contudo em baixo no grafico não actualiza… estranho
@Nuno_Figueiredo, no código que publicas-te, experimenta no fim do ficheiro retira o delay(30000); e adiciona o comando yield();
s = String(sdm.readVal(SDM220T_EXPORT_REACTIVE_ENERGY));
if (s != "nan") {
s.toCharArray(charBuf, 50);
client.publish("sdm120/export_react_en", charBuf);
Serial.print("Export reactive energy: ");
Serial.print(s);
Serial.println(" VARh");
}
Serial.println("----------------------------------------");
}
yield();
}
inverte o TX e RX e confirma que tens o RE/DE unidos ligados ao mesmo DEREPIN que escolheste.
tenho tudo como metes te no esquema! vou trocar e ver!!
Edit: troquei e nada!
tens de ter ai alguma falha :\ confirma se tens o baud rate igual no codigo e no sdm.
Obrigado a todos pela ajuda em especial ao @Nuno_Figueiredo ja funciona vou precisar de ajuda amanha para o meter no quadro. @j_assuncao podes passar o teu codigo do Ha gosto muito do look da da coisa
Fico extramemente contente de a coisa estar a bombar por esses lados, peço a ti frederico que faças o mesmo que o Nuno fez, um esquema a mão com as ligações do Wemos, pode ser em papel mesmo. Pois quero actualizar este tópico com todos os cenários possíveis.
Por ir ao meu GitHub que está lá tudo.

para quem andar a pensar em SDM ou PZEM, fica aqui uma rapida comparação.
os totais estão desalinhados, pelo que por ai nao deve ser visto, ainda ando a procura de afinar os totais do SDM.
Muito bom @Nuno_Figueiredo obrigado pela tua partilha neste tópico estou a reunir mais informação e só à espera do esquema do Frederico para actualizar o tópico.
já procurei n encontrei algumas partes tens tudo commited?
Sim, está lá tudo…
Já encontraste o que querias no meu GitHub?

ainda não encontrei só a parte do grafico mas nao a parte do mqtt
config/config_files/packages/package_electrical_consumption.yam
ja encontreo obrigado . Já agora eu tenho bi diario a nive de luz sabes como poderia fazer isso?
